Quadrilateral OPQR is inscribed in circle N, as shown below. Which of the following could be used to calculate the measure of ∠ROP? (6 points)

Circle N is shown with a quadrilateral OPQR inscribed inside it. Angle O is labeled x plus 16. Angle P is not labeled. Angle Q

Group of answer choices

(6x − 4)° + (2x + 16)° = 360°

(x + 16)° + (6x − 4)° = 360°

(6x − 4)° + (2x + 16)° = 180°

(x + 16)° + (6x − 4)° = 180°
